Title: Gearbox
IPC: B29C48/03
Filed: 1975-05-22
Abstract: 1489289 Twin-screw extruder drive PLAST-UND ELASTVERARBEITUNGSMASCHINEN - KOMBINAT KARL - MARX STADT VEB 22 May 1975 [18 June 1974] 22308/75 Heading B5A [Also in Division F2] In a torque-dividing gear transmission, which may be used to drive a screw shaft of a doublescrew extruder, a driving pinion 2 secured to an input shaft 1 on a fixed axis in a gear-box 20 is meshed bilaterally with two idler wheels 7 and 9, which each mesh with another idler wheel 13, 11, respectively, and an output shaft 14, also on a fixed axis in gear-box 20, carries a pinion 15, meshed bilaterally with the two idler wheels 13 and 11, so that partial torques are transmitted to the output shaft 14 through the parallel paths formed by the two pairs of idler wheels 7, 13 and 9, 11 respectively. In one embodiment the four idler wheels 7, 9, 13 and 11 having shafts 6, 8, 12, 10, are together carried by a movable rocker frame 5, Fig. 3, which is retained in a floating relationship to the gear-box 20 by struts 24 with hinge joints 22, 23. In another embodiment, Fig. 2 (not shown), a similar rocker frame 5 is retained in a floating relationship by parallel guideways (21) in the walls of gear-box 20. In use, the frame 5 becomes subjected to reaction forces derived from the circumferential forces present at each point where idler wheels and pinions intermesh, whereby a self-adjusting displacement of frame 5 occurs, until the partial torques in the two paths become equalized. In an alternative embodiment, Fig. 1, idler wheels 9, 11 are carried on a rocker arm 3, and wheels 7, 13 are carried on a separate rocker arm 4, with arm 3 together with shaft 8 being rotatable about one fixed axis in gear-box 20, and arm 4 together with shaft 12 being rotatable about another fixed axis, while arms 3 and 4 are linked together by a strut 18 having an adjustment member 19 and hinge joints 17. In use, arm 3 is subjected to reaction forces derived from circumferential tooth forces acting on wheel 11, and arm 4 to reaction forces related to wheel 7, whereby a joint self-adjusting displacement of the arms 3 and 4 occurs, until the partial torques become equalized. The balanced nature of the output drive torque avoids asymmetric radial loading of the shaft 14, thus permitting a compact assembly in which the bearings of shafts 1 and 14 may be of small dimensions, and a second independent output shaft 16 may be located close to shaft 14, e.g. for driving a second screw shaft in a double-screw extruder.

Abstract: 1,044,287. Endless conveyers. DAWSON, PAYNE & ELLIOT Ltd. June 29, 1965 [June 3, 1964], No. 22879/64. Heading B8A. Means for conveying hollow articles relatively to a printing or coating station, a delivery station and a feeding station includes an endless track or circuit provided with a plurality of mandrels for supporting the articles, and means for causing differential conveying movement of parts of the track. As shown, endless chains 8 support mandrels for containers 21 which, on the upper span oj the track, are continuously indexed one by one, from left to right. Upon arriving at a station " A," Fig. 1 (not shown), each mandrel and container is raised and then lowered for printing of the container by a cylinder 45. The mandrels on the lower span of the track are indexed four at one time to enable four containers to be fed on and another four to be simul-  taneously removed from the  track. Chain wheels 18 driven, e.g by a Geneva gear, move the chains 8, together with the mandrels and containers, one mandrel pitch at a time. On the lower track span, eight mandrels with their containers are depressed from their seatings on the chains 8 and are clamped between jaws 48, 49. To permit the eight mandrels to remain static while the upper section of mandrels are indexed along twice, tracks 9 for the chains 8 are moved to the right (see broken lines) by rack and segment means 11, 14. The lower eight mandrels are then unclamped and the tracks 9 moved to the left (shown in full lines), thus moving the eight mandrels four places to the left, during which time a further two containers have been processed on the upper span. The mechanism is now ready to repeat the sequence. Feed and discharge for containers.-These lie on pins on a chain 50 which is driven continuously but a portion of which, at the transfer points, is temporarily stopped. Four containers are arranged to be stationary immediately below four stationary mandrels and are displaced from the pins, either mechanically or pneumatically, into four waiting holders 51 which are then raised until the centres of the containers and the centres of the four mandrels coincide. The containers are then fed on to the mandrels, traverse the circuit, are processed, and arrive at four positions, to the right of the machine centre line, where they are removed, lowered, and fed on to four waiting pins of the conveyer chain.

Abstract: 914,901. Transistor circuits; cathode-ray tube circuits; amplitude modulation; pulsing carrier frequencies. DICK CO., A. B. July 1, 1960, No. 23060/60. Classes 40 (5), 40 (6) and 40 (7). [Also in Group XXXVIII] A circuit for providing in two output circuits pulses of opposite phase, comprises an oscillator energized through a normally closed gate which is opened by input pulses so as to permit the oscillator to oscillate, the oscillator having a tuned output transformer feeding two secondary windings connected to respective rectifiers to provide the output pulses. Fig. 2 shows an oscillator transistor 72 connected to a supply source 74 through a normally non-conducting transistor 70. Input pulses 71 render transistor 70 conducting so that oscillation occurs. The output of the oscillator is supplied to two secondary windings 82, 84 connected to oppositely directed rectifiers 104, 106 so that oppositely-phased outputs are produced. The circuit is described as applied to a cathode-ray tube apparatus in which the spot can be deflected to any one of eight horizontal positions and any one of eight vertical positions in response to a 6-unit digital code three units being used to control the horizontal position and three the vertical position. The deflection is controlled by circuits, Fig. 1, comprising two similar chains of Zener diodes 30, 32, 34 and 30<SP>1</SP>, 32<SP>1</SP>, 34<SP>1</SP>, the diode chains being connected in series with respective constant current sources 10, 12, and each diode being connected in parallel with a transistor. The corresponding transistors in the two chains are controlled in anti-phase, the transistor chains 40, 42 and 44 being normally non-conducting and the other chain conducting. The digital signals are decoded in a unit 56 and applied through units 50, 52 and 54 to the pairs of transistors so that combinations of the diodes are shorted out to provide the desired deflection voltage at 58, 60. A similar circuit 68 provides the vertical defecting voltage at 64, 66. Each of the units 50, 52 and 54 comprises a circuit as described in Fig. 2. The bias to maintain the transistors on the right-hand chain normally non-conducting is derived across a silicon rectifier 134 (Fig. 2), connected to a voltage source 120 and is in series with the pulse output circuit.
